Earlier this month, cleantech startup Clearloop broke ground on a 1‑megawatt solar project outside Jackson, Tennessee that stakes out a bold new definition of solar’s carbon-reduction value. It’s the first utility-scale solar project in the country to be partially financed by selling the carbon emissions it will displace over its lifetime. These transactions will not take the customary form of renewable energy credits that average out that value over time, but rather of carbon offsets that are directly related to the power grid the project is connected to.  In more specific terms, about $400,000, or roughly one-third of the project’s cost, was raised via the sale of offsets for nearly 60 million pounds of carbon emissions.

The aim of the financial declaration clauses is to provide social pressure to make sure donations happen. This clause doesn't require anybody to make a donation to the DSF - there's no mandatory license fee for any use of the Django mark. However, if you want to use the Django name or logo, you do have to publicly declare that you're not giving anything back to the project. The hope is that this will provide enough social pressure to encourage some level of contribution back to the DSF.

... I'm not happy with the way an event/group handled my code of conduct complaint? The first line for reporting any code of conduct violation should always be the event or group organizers themselves. However, if you've done this, and you're not happy with the response you've received, contact the DSF by email: foundation@djangoproject.com and the DSF will investigate and respond. In the extreme case, this response may be to revoke the group/events license to use the Django name

You must also adopt a code of conduct (the Ada initiative draft is a good starting point, but you can choose another code if you wish), and agree to run your event in the spirit of the Django Community code of conduct.

Originally, Google was building flying cell towers to beam down the Internet from the sky (over RF), but for balloon-to-balloon backhaul, the company was planning communications via laser beam. Space X just started doing something similar by equipping its Starlink satellites with space lasers for optical intra-satellite communication. One benefit of Sky- and space-based laser communication is that not much can interfere with a point-to-point optical beam. Ground-based lasers have more interference to consider, since they have to deal with nearly everything: rain, fog, birds, and once, according to Alphabet's blog post, "a curious monkey."

For example, a 1:1 HD 1080p video meeting of 1 hour between two people would require 3.24GB of bandwidth, consuming 0.0486 kWh of electricity. The 2019 UK electricity emissions factor is 0.25358 kgCO2 per kWh, so the CO2 emissions for this call are 0.012 kgCO2. If this happened in the US between two people in New York, the emissions factor is similar to the UK at 0.28839 kgCO2 per kWh but if it was between two people in Chicago, that would be 0.56191 kgCO2 per kWh. Location matters.

My estimate of 36gCO2 per hour is more than 2,100-times lower than Marks et al. (2020) who estimated that 35 hours of HD video emits 2.68tCO2, or 77kgCO2 per hour.

a result, the central IEA estimate for one hour of streaming video in 2019 is now 36gCO2, down from 82gCO2 in the original analysis published in February 2020.

t’s not actually going to be a standard, per se, because you can’t pass regulatory standards through reconciliation. Instead, it’s going to be a system of fines and payments that will incentivize utilities to increase their proportion of renewable energy to meet the targets. It’s called a clean electricity payment program (CEPP). A CEPP actually has some advantages over the traditional CES’s and renewable portfolio standard (RPSs) commonly seen in states. For one thing, it’s more progressive: the money to drive the transition comes from federal coffers (via taxes on corporations and the wealthy) rather than from electricity rates, which are regressive.

With a drink containing approximately 18 g of green coffee (Starbucks Coffee Company, 2019), each kg of green coffee makes approximately 56 espresso beverages. Thus, the carbon footprint found in the LCA is on average 0.28 and 0.06 kg CO2e per espresso beverage for conventional and sustainable coffee, respectively (9.2 and 2.1 g CO2e ml–1). In an LCA of milk production, Hassard et al. (2014) estimated a carbon footprint of 2.26 g CO2e ml–1. Using these values, the carbon footprint of standard coffee beverages was estimated: with the conventional production of coffee beans, the carbon footprints for one serving of caffe latte, flat white, and cappuccino were estimated to be 0.55, 0.34, and 0.41 kg CO2e, respectively. When produced sustainably, these values were reduced to 0.33, 0.13, and 0.20 kg CO2e

Renewable energy surcharge (21%) Finances the feed-in tariffs for renewable power and the market premium paid to larger producers - 6.41 ct/kWh.

In the 2014 Radio Equipment Directive, EU lawmakers called for a common charger to be developed and gave the Commission powers to pursue this via a delegated act. The Commission's approach of “encouraging” industry to develop common chargers fell short of the co-legislators’ objectives. However, some progress has been made, said the Commission in the plenary debate on 13 January 2020: in 2009, there were more than 30 charging solutions, while today there are three charger types. In its resolution on the European Green Deal, Parliament called for an ambitious new circular economy action plan aiming to reduce the total environmental and resource footprint of EU production and consumption, with resource efficiency, zero pollution and waste prevention as key priorities.

This article derives criteria to identify accurate estimates over time and provides a new estimate of 0.06 kWh/GB for 2015. By retroactively applying our criteria to existing studies, we were able to determine that the electricity intensity of data transmission (core and fixed-line access networks) has decreased by half approximately every 2 years since 2000 (for developed countries), a rate of change comparable to that found in the efficiency of computing more generally.

Global data centre energy demand by data centre type, 2010-2022

As the graph above shows, renewables will need to do the heavy lifting, growing even faster than in recent years. By 2050, says the IEA, around 90 per cent of global electricity supply will need to be low carbon, about 70 per cent from solar and wind power, with the rest mostly from nuclear.

The average cup of coffee contains about 18g of green coffee, so 1 kg of it can make 56 espressos. Just one espresso has an average carbon footprint of about 0.28 kg, but it could be as little as 0.06 kg if grown sustainably.

Climate protection is a human right and must be included in the constitution

But I'm wondering if VC-backed firms should be excluded from projects that require long-term maintenance because their growth requirements (fiduciary duties to investors, aka "we need a hockey stick") means they can't commit to 10-20 year contracts?

2020 is the year in which the current Dutch subsidy scheme for renewable energy, the Renewable Energy Production Incentive Scheme (de stimuleringsregeling duurzame energieproductie (SDE+)), will change. From 2020 onwards, the SDE + will be broadened to achieve the target of a 49 percent reduction in CO2 emissions in the Netherlands by 2030 (or at least to keep this goal within reach). The broadened SDE+ focuses on the reduction of greenhouse gas emissions (CO2 and other greenhouse gases). This will change the focus from energy production to energy transition. The broadened subsidy scheme is therefore called the Renewable Energy Transition Incentive Scheme (SDE++).

Air pollution caused by the burning of fossil fuels such as coal and oil was responsible for 8.7m deaths globally in 2018, a staggering one in five of all people who died that year, new research has found.

Currently, there is a significant lack of transparency of environmental cost, which should be urgently resolved given the vast scale of resource usage. Therefore, NGIatlantic.eu invites EU – US applicants that can provide and experiment with transparency mechanisms on the environmental cost of the Internet. Identification and tagging of most resource consuming elements are also very important and urgent. On both sides of the Atlantic, there has already been some early research and innovation projects and initiatives focussing on alternatives to improving energy efficiency to ensure the greening and sustainability of the Internet and of the economy relying on it. This topic welcomes the results from these EU activities to team up with US teams (or vice versa, with US teams twinning with EU teams) to carry out experiments in this vitally important NGI topic.

That will allow the utility to match in real-time specific units of renewable energy generation with Microsoft’s usage – and dispatch energy from storage if there’s a shortfall – to ensure Microsoft is continually supplied with renewable energy, Janous said.

Typically, a data center is seen as an inflexible load, or a “single block” of power, she said. In other words, if the facility’s total load is 10MW, the conventional approach is to ensure there’s 10MW of backup power. Google has learned to not treat total load as an inflexible block and match backup capacity more tightly with the capacity required by applications that run in the facility and the duration for which it’s required.

Also this year, Microsoft announced a successful test for powering a data center rack with a hydrogen-fueled automotive fuel cell, looking at the technology as one of the potential replacements for diesel generators.

Google estimates that the total generation capacity of all diesel-fueled data center backup generators deployed worldwide is more than 20 gigawatts, which could spell vast opportunities for renewable energy storage.

But proponents of immersion cooling technologies emphasize their efficiency advantages. These solutions don’t require any fans. Server fans are usually removed altogether. “You can probably get at least a 15-percent energy reduction in a lot of environments by going to liquid cooling,” Brown said.

As Uptime’s Lawrence pointed out, generators are “a problem.” They are expensive to deploy and maintain, they pollute the atmosphere, and make a lot of noise. So far, however, they’ve been an indispensable part of any data center that’s meant to keep running around the clock.

Perhaps the most critical feature of a decentralized UPS architecture is it allows data centers to meet increased demand by deploying equipment-specific resources that can scale according to needs. New cabinets can expand capacity as necessary, while additional rectifiers and battery modules can increase power for servers added to open racks. By relying on DC power components that connect directly to the AC utility feed, a decentralized power architecture allows facilities to operationalize stranded white space and maximize infrastructure without placing any additional strain on their existing UPS system.

I'm really curious whether or how creating more effective car battery recycling technologies could support or underwrite consumer electronics recycling. For years, the line on e-waste has been that the economic model for electronics recycling just doesn't work. As devices get smaller, extraction gets more time-consuming and with increased component miniaturization, recycling companies are getting less and less value from what metal they can recover (although notably, Redwood Materials is refining their battery recycling process through recycling consumer electronics). Recycling car batteries at scale fills a massive need and companies will definitely pay for those materials. If Redwood can get it right, they could potentially make a less-profitable recycling niche more viable with the resources afforded by its primary more profitable niche.

In addition, the recent need to accelerate deep-learning and artificial intelligence applications has led to the emergence of specialized accelerator hardware, including graphics processing units (GPUs), tensor processing units (TPUs) and field-programmable gate arrays (FPGAs). Owing to its in-memory data model, NumPy is currently unable to directly utilize such storage and specialized hardware. However, both distributed data and also the parallel execution of GPUs, TPUs and FPGAs map well to the paradigm of array programming: therefore leading to a gap between available modern hardware architectures and the tools necessary to leverage their computational power.

NumPy operates on in-memory arrays using the central processing unit (CPU). To utilize modern, specialized storage and hardware, there has been a recent proliferation of Python array packages

his dream of it being as easy to “insert facts, data, and models in political discussion as it is to insert emoji” 😉 speaks to a sort of consumerist, on-demand thirst for snippets, rather than a deep understanding of complexity. It’s app-informed, drag-and-drop data for instant government.

The set-up of a cloud services marketplace for EU users from the private and public sector will be facilitated by the Commission by Q4 2022. The marketplace will put potential users (in particular the public sector and SMEs) in the position to select cloud processing, software and platform service offerings that comply with a number of requirements in areas like data protection, security, data portability, energy efficiency and market practice.

In France, as in other Western countries, for various reasons too long to mention in this study, the collection level of waste electrical and electronic equipment is around 45%.

Had they been implemented as of 2010, these 4 measures would have reduced the global digital footprint over the period observed (2010 to 2025) by between 27% and 52%

Reducing the number of flat screens by replacing them with other display devices such as augmented / virtual reality glasses, LED video projectors, etc.

Their contribution to the impact of the digital world thus goes f rom less than 1% (all environmental indicators combined) in 2010 to between 18% and 23% in 2025. It is huge!

In 2025, user equipment will concentrate from 56% to 69% of the impact. For example, 62% of digital GHG emissions will be user-related, 35% of which comes from equipment manufacturing.

The hierarchy of impact sources is as follows, in descending order of importance:1. Manufacturing of user equipment;2. Power consumption of user equipment;

In 2019, the mass of this digital world amounts to 223 million tonnes, the equivalent of 179 million cars of 1.3 tonnes (5 times the number of cars in France).

This framework tends to follow a similar pattern which includes most or all of the following steps: set goals and define scope, inventory analysis, impact assessment, interpretation, reporting and critical review.

Even the OECD definition of ICT includes a whole range of consumer electronic (CE) products that many would not expect to see classed as ICT.

And with carbon, as with calories, it is the pies –or rather their carbon equivalents -that are important. LCA is a poor tool for differentiating between strawberries and raspberries, but it is a wonderful tool for identifying where the pies are, and who is eating them

The action was the digital equivalent of queueing up at McDonalds and ordering the non-existent vegan, zero-waste Happy Meal again and again. Rebels targeted a different polluter each day, including fossil fuel companies Shell and BP, shipping company Maersk, and the Danish Finance Ministry for its recent bailout of Scandinavian Airlines.

Technological improvements also play a role in driving down battery costs. Frith points out that the term lithium-ion battery is actually an umbrella term for a number of different battery chemistries.

Displace dirty energy demand: New renewables supply displaces demand for existing dirty electricity generation.

The Oil Climate Index from the Carnegie Institution gives full lifecycle emissions for a selection of global crude oils. That analysis does not specifically profile Permian crude oils, but does find that the median U.S. crude oil will lead to 0.51 metric tons of CO2-eq over its lifecycle.[

She labelled this phenomenon “socially organised denial”.

With the backing of Green Alliance and some philanthropic funders, I set up a training programme. We offered parliamentary candidates and new MPs the chance to learn about the science, policy and politics of climate in a series of tailor-made workshops. We worked with small groups of around 10 politicians, all from the same party, to allow them to question and debate freely.

Strengthening: The team understands its role in the larger organizational system and actively works to make that system more successful.

Although you may be tempted to hire new employees to fill the gaps, it’s usually more effective to include employees who already understand your business’s unique priorities and constraints.

team chartering

Each fluency zone brings new benefits, so it may seem that the model should be treated as a maturity model, in which the goal is to reach maximum maturity. That would be a mistake. Unlike maturity models, where more mature is always better, the fluency model describes a collection of choices. Each zone represents a fully-mature choice. Each one brings value.

Although teams develop proficiencies in any order, even from multiple zones simultaneously, we’ve observed that teams tend to gain zone fluency in a predictable order.

Focusing teams produce business value. Delivering teams deliver on the market cadence. Optimizing teams lead their market. Strengthening teams make their organizations stronger

For example, the GUI tool for PostgreSQL administration, PGAdmin 3, is used by many people.  (I’m an old-school Unix guy, and thus prefer the textual “psql” client.)  I’ve discovered over the years that while PGAdmin might be a useful and friendly way to manage your databases, it also automatically uses double quotes when creating tables.  This means that if you create a table with PGAdmin, you might find yourself struggling to find or query it afterwards.

Averylarge data centre may consume 30GWh of power in a year, costing its operator around £3,000,000 for electricityalone. A handful of sites in the UK consume even more than this although the majority of sites consume far less. The total power demand of the UK data centre sector is between 2-3TWh per year2. Energy is usually the largest single element of operating costs for data centres, varying from 25-60%.

In this case, establishing a direct connection between thepeers seems to be impossible, and the only remaining op-tion is to use a server with a public IP address to proxythe communication between the peers, e.g. using the TURNprotocol [18]

For ephemeral updates PushPin uses an additional mes-saging channel, adjacent to the CRDT, which ties arbitrarymessages to a device and user context. The current implemen-tation is rudimentary: ephemeral data is not associated witha particular CRDT state and is distributed only over directP2P connections. Nevertheless, it enables shared contextualawareness in the user experience of PushPin, providing afeeling of presence when other users are online or collabo-rating

Each URL also includes acontentTypeparameter, whichindicates how that document should be rendered in the userinterface. This parameter is part of the URL, not the docu-ment content, because the same document content may berendered differently in different contexts. For example, Push-Pin could be extended to support flashcards for languagelearning. In one context, the document containing the data-base of flashcards could be rendered as a list of entries, whilein another context it might be rendered as a quiz interface,presenting one side of one flashcard at a time.

People make light of the idea that digital should be the most basic of Maslow’s hierarchy of needs — over food, water, shelter, and warmth — but there is evidence that people do, to an extent, prioritise connectivity over food and comfort. Some refugees, for instance, are known to have asked for Wi-Fi or charging services ahead of food or water on arrival in a new country.

Globally, Amazon has 86 solar and wind projects that have the capacity to generate over 2,300 MW and deliver more than 6.3 million MWh of energy annually—enough to power more than 580,000 U.S. homes.

Additionally the image registry can be monitored to find new versions of images to deploy.

For now, suffice it to say that Tailscale uses several very advanced techniques, based on the Internet STUN and ICE standards, to make these connections work even though you wouldn’t think it should be possible. This avoids the need for firewall configurations or any public-facing open ports, and thus greatly reduces the potential for human error.

Here’s what happens: Each node generates a random public/private keypair for itself, and associates the public key with its identity (see login, below). The node contacts the coordination server and leaves its public key and a note about where that node can currently be found, and what domain it’s in. The node downloads a list of public keys and addresses in its domain, which have been left on the coordination server by other nodes. The node configures its WireGuard instance with the appropriate set of public keys.

Sadly, developers have stopped building peer-to-peer apps because the modern Internet’s architecture has evolved, almost by accident, entirely into this kind of hub-and-spoke design, usually with the major cloud providers in the center charging rent.

A breadcrumb in this case is a single pixel that you can place in a precise location on a webpage. Placing a breadcrumb could be as simple as Option + click. While navigating the web, you could leave breadcrumbs on different pages you find interesting over the course of a browsing session. When you're done, that sequential "trail of breadcrumbs" would be saved. You could then jump back into the trail and navigate "forward" and "backward" through the things you found interesting in that browsing session. Or share the trail with a friend, and they could step through your spatial path of navigating the web.

When you run a standup at a technology company, you typically go around a circle and each person gives their daily update. But in Zoom, there is no circle. You get confused about who is next. Two people start speaking at the same time. It's awkward and confusing. Eventually, you realize that one person, probably the manager, just has to dictate who goes next, at the risk of seeming bossy.

Since emission reduction projects registered under crediting programmes to date have been mostly developed in the context of cost-saving, rather than ambition-raising mechanisms, we understand that there are very few, if any, examples of existing credited projects that represent those high-hanging fruits, and which could be considered truly additional in the context of the Paris Agreement. Given the difficulty in objectively determining additionality in line with this definition, we consider that only a niche and ever reducing number of activities could count for this, and that this does therefore not represent a viable option for rapidly increasing demand volume of the market.

A climate responsibility approach needs to first and foremost incentivise and facilitate the reduction of one’s own emissions.

Emissions from project-specific activities, such as project-related travel, are attributed as cost items to their respective project cost lines.

We recognise that some of the activities with the highest transformation potential – and therefore with high suitability for supporting the objectives of the Paris Agreement – may be at early stages of development and/or may carry a risk of not delivering attributable emission reductions.

The High-Level Commission on Carbon Prices surveyed the available scientific literature, concluding that the explicit carbon-price level consistent with the Paris Agreement temperature objectives is at least US$40–80/tCO2 by 2020, provided that a supportive policy environment is in place (High-Level Commission on Carbon Prices, 2017). Informed by this report and allowing for its uncertainties, NewClimate Institute has imposed a price level of EUR 100/tCO2e for the 2014-2019 period. This is also in-line with the central estimate of climate change avoidance costs over the period to 2030 used in the European Commission’s 2019 Handbook on the External Costs of Transport (European Commission, 2019).

This methodology for the estimation of GHG emissions includes the estimated equivalent climate impact of non-carbon climate forcers from aviation, such as condensation trails, ice clouds and ozone generated by nitrogen oxides and results in emission estimates approximately three times greater than if calculating only direct CO2 emissions (Atmosfair, 2016).

For the moment, the main take-away is that there is a goodargument that registration fees should ​not​​be set at $0, even this year. Rather, organizersshould look at their existing budgets, and rework them by eliminating the costs associated withthe physical event. Virtual conferences that do choose to set their prices low should be carefulnot to encourage an expectation that other virtual conferences (or future instances of this one)will always be free or cheap. (For example, one of the suggestions heard by the ASPLOSorganizers was “keep it free;” obviously, this may not be financially sustainable.)

He mentioned a few examples where the AI fallacy is already playing out. One is the idea from the national statistician that we might not need to keep doing a census, because there will be lots of data from other sources. Neil pointed out that we actually need more classical statistics than ever, to verify all this machine learning and data. He calls this the “Big Data Paradox” - that as we measure more about society, we understand less. We need to be able to sanity check our large complex systems - the census is still valuable.

In the section on technical debt, the mythical man month, etc, I was amused to note that Neil called out Amazon's fabled "two pizza team" as American cultural imperialism. The problem arising from the separation of concerns and specialisation of teams is that no one is concerned with the whole system.

Methodology and sources The analysis of the carbon intensity of streaming video presented in this piece is based on a range of sources and assumptions, calculated for 2019 or the latest year possible. Bitrate: global weighted average calculated based on subscriptions by country and average country-level data streaming rates from Netflix in 2019; resolution-specific bitrates from Netflix.Data centres: low estimate based on Netflix reported direct and indirect electricity consumption in 2019, viewing statistics and global weighted average bitrate (above); high estimate based on 2019 cloud data centre IP traffic from Cisco and energy use estimates for cloud and hyperscale from IEA.Data transmission networks: calculations based on Aslan et al. (2017), Schien & Priest (2014), Schien et al. (2015), and Andrae & Edler (2015), and weighted based on Netflix viewing data by devices. Devices: smartphones and tablets: calculations based on Urban et al. (2014) and Urban et al.

(2016), and weighted based on Netflix viewing data by devices. Carbon intensity of electricity: based on IEA country-level and global data, and 2030 scenario projections.

Aristotle’s view of the process: “We are what we repeatedly do. Excellence, then, is not an act but a habit.”

Buying carbon offsets might still have greater impact in the short run, but you can’t see them, so their purchase is less likely to be contagious.

Today the average carbon intensity of electricity generated is 475 gCO2/kWh, a 10% improvement on the intensity from 2010.

It is relevant to estimate how much data is generated by - and associated electric power used - normal behavior like video streaming several hours every day.

So energy consumption in the oil and gas sector, into which Google Cloud is selling its cost-reducing services, is four orders of magnitude larger than Google’s data center decarbonization efforts. The harm that Google Cloud will do to the planet, if it reduces underlying costs of this industry by even a small percent, completely dwarfs the data center decarbonization work.

Therefore, we estimate an advertising share of 50% for the traffic class web, email, and data in 2016, with an uncertainty range of [25%–75%]. The share is the same for both mobile and fixed traffic.

According to a Solarwinds company 2018 study, the average load time for the top 50 websites was 9.46 s with trackers and 2.69 s without.

The Internet's share of the global electricity consumption was 10% in 2014 (Mills, 2013): As a reference, the entire global residential space heating in 2014 consumed the same amount (International Energy Agency, 2017a).

. In particular,on the host, we propose a first configuration of a software-defined power meter that builds on a new CPU power modelthat accounts for common power-aware features of multi-core processors to deliver accurate power estimations at thegranularity of a software process. In the VM, we introduce asecond configuration of a software-defined power meter thatconnects to the host configuration in order to distribute thepower consumption of VM instances between the hosted ap-plications. The proposed configuration can even be extendedto consider distributed power monitoring scenarios involvingapplication components spread across several host machines.

WhileBITWATTSis a modular framework that can accom-modate different power models (includingrunning averagepower limit(RAPL) probes and power meters), we propose aprocess-level power model, which is application-agnostic andaccounts for virtualization—i.e., for emulated cores withina VM—and for the power-aware extensions of modern pro-cessors, notably hardware threading anddynamic voltageand frequency scaling(DVFS).

For Apple, this may be a feature rather than a bug: Documents obtained by Motherboard in 2017 revealed that the company requires its recycling partners to shred iPhones and MacBooks so that their components cannot be reused, further reducing the value recyclers can get out.

So, Apple has started collecting that scrap, melting it down and forming new hunks of aluminum that can be used to carve more gadget husks.

In February 2018, she published a report — titled Mission-Oriented Research & Innovation in the European Union — that defined five criteria missions should obey: they must be bold and inspire citizens; be ambitious and risky; have a clear target and deadline (you have to be able to unambiguously answer whether the mission was accomplished to deadline or not, Mazzucato says); be cross-disciplinary and cross-sectorial (eradicating cancer, for example, would require innovation in healthcare, nutrition, artificial intelligence and pharmaceuticals); and allow for experimentation and multiple attempts at a solution, rather than be micromanaged top-down by a government.

Mazzucato traced the provenance of every technology that made the iPhone. The HTTP protocol, of course, had been developed by British scientist Tim Berners-Lee and implemented on the computers at CERN, in Geneva. The internet began as a network of computers called Arpanet, funded by the US Department of Defense (DoD) in the 60s to solve the problem of satellite communication. The DoD was also behind the development of GPS during the 70s, initially to determine the location of military equipment. The hard disk drive, microprocessors, memory chips and LCD display had also been funded by the DoD. Siri was the outcome of a Stanford Research Institute project to develop a virtual assistant for military staff, commissioned by the Defense Advanced Research Projects Agency (DARPA). The touchscreen was the result of graduate research at the University of Delaware, funded by the National Science Foundation and the CIA.

Just this month it was announced that over half of the power plants operated by China’s Big Five state-owned utilities are running at a loss. The government has plans for up to one third of them to shut by 2021, removing 15% of the country’s coal capacity.

No matter that there is no single robust methodology: internalizing Carney’s three types of climate risk – physical, liability and transition – will inevitably work through to large-scale asset disposals and new reinvestments; it will without doubt affect the cost of capital of high-carbon businesses.

No single “sneeze” will wipe out fossil fuel use across energy and transport; It will occur sector by sector, country by country. Over the past six years, LED light-bulbs have gone from less than 5% global market share to over 40%; coal power in the U.K. from 40% to a couple of percent; plug-in vehicles in Norway from less than 5% to over 50%. In each case, there was a slow start, an agonizing wait, and then the sneeze. Bless you!

The average capacity factor of the world’s hydro plants is 42%; gas peaking plants 15%. Even so-called baseload coal plants run on average only 54% of the time. If technology is cheap, and demand or supply are intermittent, we overbuild. Wind and solar are no different.

Starting with a small cohort, we’ll refine the patterns and practices that sustain learning. We will see case studies of how the organizing model is made locally relevant. Globally, we will be a large peer learning community. And we’ll also have smaller, local peer learning communities connected and experimenting in a place.

For our community that teaches the web, we understand ourselves as participating in i) a global network and ii) a local context.

However, to be accurate and relevant, GHG inventories must reflect the emissions caused by the reporting entity. The fundamental issue with the contractual method is that it does not represent any causal relationship between the reporting entity and the emissions reported.

The distinction between attributional and consequential GHG accounting is well understood in some fields, such as life cycle assessment (LCA), but much less so in the area of corporate GHG accounting, which has traditionally used attributional accounting (Brander et al., 2015).

However, in reality, contractual emission factors represent a market failure, because the implied goal (actual reduction of emissions to the atmosphere) is in fact not delivered by contractual emission factors (as discussed in Section 2), and therefore the approach has only the appearance, and not the substance, of a market-based solution.

Further, for Company A's use of contractual emission factors not to lead to double-counting of the claimed renewable attributes, the method requires all other reporting entities to also apply a ‘residual grid mix’ emission factor. As this emission factor would be higher than the grid average, due to removing some renewable generation from the calculation, Company B's performance is again made to look worse, although its actual contribution to reducing emissions is greater than Company A's.

Electricity generation accounts for approximately 25% of global greenhouse gas (GHG) emissions, with more than two-thirds of this electricity consumed by commercial or industrial users

This issue is highly topical as recently published reporting guidance from the GHG Protocol (WRI, 2015) has endorsed the market-based approach, while the forthcoming update of ISO 14064-1 for corporate GHG inventories provides an opportunity to establish a more robust approach.

The GHG Protocol's Scope 2 Guidance, published in 2015, requires that companies use both the locational grid average method and the market-based method to report scope 2 emissions (i.e. dual reporting). However, the guidance also allows companies to choose a single method for meeting their reduction targets and for reporting their supply chain emissions (WRI, 2015). The same guidance has been adopted by CDP, formerly the Carbon Disclosure Project (CDP, 2016a).

Moreover, in many countries the amount of renewable generation is increasing due to the other drivers, such as government subsidies (IEA, 2016b), and therefore the point at which additionality might be achieved (i.e. beyond Q1) is continually advancing further beyond the reach of voluntary market demand for contractual emission factors.

ET Index Research data, which includes 2000 of the world's largest listed companies, shows 97 companies using the market-based accounting method to report lower emissions, equating to 22.2 million tCO2e/yr.2 This approximates to ~ 1% of globally available renewable electricity generation in 2015,3 and therefore demand for contractual emission factors would need to increase a hundred-fold to reach the existing supply threshold for renewable attributes (which is continually increasing anyway), and only once above that threshold would demand cause a fractional increase in renewable generation.

Chris Adams, a web designer and climate activist in Berlin, tells me he thinks a green internet must be free of advertising. “Ninety percent of a web page being ads requires servers, and those servers are taking electricity, and that electricity is generated by burning coal,” he says. Adams has written that the European site for USA Today is a model of efficiency. It removed all of its tracking scripts and ads to be compliant with recent General Data Protection Regulation legislation in the European Union. The site size immediately shrank from 5 megabytes to 500 kilobytes, but it still basically looks the same—there are just no ads.

Describing the move as an industry first, Repsol said it wanted to lead a wider transition to renewable energy, in line with the goals of the 2015 Paris Agreement to avert catastrophic climate change.

Giving extra impetus to its new goals, Repsol will link at least 40% of managers’ long-term variable pay to its emissions reduction targets.

Build on narrative that integrates the two approaches, probably building oncircularity (be part of the coming standard) and efficiency of services (e.g. theexample of interface not knowing their impact in services besides havingenvironmental product declarations for all their products).

In short, Nordhaus, who is mentioned both in my 2007 and 2012 pieces, tells us not to worry too much about climate change. It will be cheaper to adapt to it than to prevent it or slow it down.

Basically, all services in public administration will moveinto the cloud, which means that a huge amount of data will be digitalised. This has huge implications forthe security of the data (which can quickly translate into national security matters). Most of the services are now provided by companies outside Europe, which raises questions aboutdata sovereignty, ownership, transpar-ency, etc. Also, as recently proposed by Germany (GAIA-X project), the European Union should re-gard the cloud as a critical infrastructure which should be developed within Europe.

Almost a third of UK boards (32%) feel little or no responsibility for the climate crisis, according to a global survey of 640 chairs and non-executive directors by recruitment firm Harvey Nash and London Business School’s Leadership Institute.

The emissions from onereturn ticket from London to New York are roughly equivalent to that of heating a typical home in the EU for a whole year (European Commission, 2019).

Those instances of decoupling that can be observed (like the UK or Germany in past years) result mainly from deindustrialisation and the outsourcing of energy-intensive industrial production to other countries.

easyJet’s aircraft carbon emissions in the 2018 financial year were 7.6 million tonnes, compared to 7.1 million tonnes in the 2017 financial year. easyJet’s calculation of emissions is based on fuel burn measurement, which complies with the EU’s Emissions Trading System requirements.

More figures extracted from the EURECA project, 2018. 40% of servers in public sector data centres were over 5 years old. These performed 7% of compute but used 66% of power.

UK Government departments are required to report energy usage and explain how they are reducing their respective carbon footprints and this obligation to understand and report scope 3 emissions is likely to become more widespread, given UK government commitments to climate change targets and increasing observance of UN Sustainable Development Goals (SDGs). It is also a requirement of the Science Based Targets methodology.

Amazon's carbon intensity metric, measured as grams carbon dioxide equivalent (CO2e) per dollar of Gross Merchandise Sales (GMS), equals 128.9 g CO2e per dollar (USD).

For example, spending on parcel delivery by third-party carriers is mapped to the couriers and messengers sector (i.e., 224 grams of CO₂e per dollar) and shipping boxes are mapped to paperboard container manufacturing (i.e., 807 grams of CO₂e per dollar).

However, the table and figure below both use 2012 datapublished in 2014for all three different approaches to reporting emissions.

If the current de-velopments determined by Borderstep continue, the energy consumption of data centers will double by 2030 compared to today.

While Shehabi et al. assume that maximum power consumptionis constant[4], the Borderstep model assumes an increase in maximum power consumption due to a significant increase in the average amount of RAMs and multiprocessor systems.

According to a Borderstep Instituteestimate, worldwide energy consumption of server data centers increased by about 30% to 287 billion kWh between 2010 and 2015 [9]. This in-crease accelerated once again in the last two years. A current TEMPRO project estimate concludes that between 2015 and 2017 theenergy consumption of data centers worldwide in-creased by approx. 20% to 350 billion kWh

The analyses and results presented in this article were pro-duced as part of the project TEMPRO –"Total Energy Man-agement for professional data centers." TEMPRO is supported through the 6th Energy Research Programme of the German FederalGovernment.

Online video viewing, which represents 60% of the world’s data traffic, generated more than 300 MtCO2e during 2018, i.e. a carbon footprint comparable to the annual emissions of Spain
